I am after a DK Beat Paramotor which is the twin cylinder direct drive tiny paramotor unit. Any condition considered. Think its from the 90's

Hi guys, a quick question about the RAD ARROW Paramotor. I bought an arrow Paramotor a while back but I later found out it has had a new engine fitted, this engine is the same Racket 120cc but the belt reduction ratio is wrong and the prop is the wrong size. I am trying to put this back to RAD standard configuration but I need to know what the belt reduction is. My motor currently is 3:1 reduction but I know the arrow is either 3.3:1 or 4:1 I wonder of any of you guys knows or even has one and can count the reduction? I tried contacting RAD but they seem to think its a huge secret and won't tell me. Also Info of which helix propeller they use would be good. Regards Gareth
